Title On the Impossibility of Global Stabilization of the Lagrange Top
Author(s) I.Yu. Polekhin (Steklov Mathematical Institute of the Russian Academy of Sciences, Moscow, 119991 Russia, ivanpolekhin@mi-ras.ru)
Abstract It is shown that the problem of the asymptotic stabilization of a given position of the Lagrange top for any control from a sufficiently wide class does not permit the existence of a single uniformly asymptotically stable equilibrium, even with possible impacts of the top against the horizontal plane; i.e., the global stabilization of the system is impossible. In particular, we show that it is impossible to globally stabilize the top by moving its pivot point along the horizontal plane.
